But it seems Benedict Cumberbatch’s uncanny resemblance to his subject may be down to more than just good acting…because it turns out they are related.
The actor, 38, is a distant cousin of the celebrated mathematician, who broke the German Enigma code during World War Two.
Both men share a common 15th century ancestor, John Beaufort, the Earl of Somerset, making them cousins 17 times removed on his father’s side, experts from the genealogy website Ancestry said.
Somewhere in the back of my mind I’ve got the idea that by the time you reach 12th or 13th cousins then certainly near all Brits meet that and by the time we reach 16th we’re getting towards all human beings, aren’t we?
OK, maybe not the Andaman Islander and the Finn but there is some point where “cousinry to the nth degree” includes most of humanity, isn’t there?
